# Calculate Date Differences: Time In & Time Out

Aug 11, 2006
I'm trying to devise a formula to produce "days in inventory" based on the following data:

Date In

Date Out (which may be blank if cargo still here)

Todays Date

Days in Whse (which is the formula I can't figure out!)

It needs to work like this, date out - date in, unless date out is null. If date out is null, the result should be calculated based off of todays date - date in.

Within 4 columns, I have a series of:

Start Dates / Start Times / End Dates / End Times

I need to create a formula which will give me the sum total of the difference between the data sets.

For example, the time difference between 8am on the 20th March and 1pm on the 21st March is 29 hours OR 1 day and 5 hours.

I need a formula which will calculate this for me.

I am wondering if there is way to analayse date and time data in a way that would allow me to look at time differences.

I have two columns of data, one has the date and time an entry was made onto a client database, the other shows the date and time an amendment or deletion was made.

What I would like is a formula that shows the time period difference between the two entries.

So for example if one column shows 14/02/2014 14:26 and the other shows 14/02/2014 14:28 it would show 1 (minute) as the result.

I have over 1000 entries to look at and manually it is taking a looooooooong time!

see the attached workbook with two different sheets (same data) using different formulas. Each has problems (red text) preventing me from moving forward.

I need to calculate time in level 1, time in level 2 and total time for each row and then be able to sum for the month. Unfortunately, sometimes there is missing data, but I still need to calculate everything possible using a consistent formula that can be applied to the column/row universally.

I have two identical web query's on the same sheet. One from column A to column I and the other one from column K to column S, and both have 404 rows. The one on the left (from column A to I) autorefreshes every 60 minutes and the one on the right (from column K to S) autorefreshes every 4 minutes. I want to subtract the numbers in column Q from column G and the ones in column R from column H, and in both cases if the result is bigger than 0 to place a timestamp in column Y(for Q-G), and in column Z (for R-H). I tried with NOW formula, but the timestamp changed every time the web query from the right autorefreshed, no matter of the result. I guess that I have to use VBA codes...but I'm not good at that .

I want to be able to calculate a due date two days from an entered date/time. If I input 9/3/2009 3:00 PM into cell F6 I would like cell G6 to display 9/5/2009 3:00 PM. The formula that I am currently using includes a holiday list so if the due date lands on a day within that list it gets pushed out.

My formula is =if(F6="","",Workday(F6,2,Z1:Z144)).

Basically when F6 gets populated G6 is supposed to populate with a due date of two days later (same time of the day). Currently if my input date/time is 9/3/2009 3:00 PM the formula is displaying a due date of 9/5/2009 12:00 AM.

I am trying to figure a way to search for a cell that has a specific date and time range. There are several cell titles pending on the activity. I want to find a cell that has a time ** 7:30-15:30 , 15:31-17:30, 17:31-20:30. The end result is to calculate the activity between those time periods based on the data cells.

Example

If the date searched time field ** the activity ranges is 1635 I need to split the time and credit the activity time in the 730-1530 time and the rest on the 15:31-17:30 time

I have been able to do it on a single labor group based on time alone, but when I try to add the DATE to it my numbers go null. Eventually i will need to add 11 labor groups daily for weeks at a time .

I am trying to use and if formula to see if the time on the cell was before a certain time.

The date is entered on Cell A2 - down and I would like to enter a formula in Cell B2 to say if the time on A2 is before 12pm as an example, "Complete" otherwise "Incomplete"

Example 1

Cell A2 : 01/10/2013 13:08:00

Cell B2 formula result: "Incomplete" (Because it was after 12pm)

Example 2

Cell A2 : 04/10/2013 10:05:00

Cell B2 formula result: "Complete" (Because it was before 12pm)

I am wanting to calculate the the processing time for an order that takes place within normal business hours and workweek. A normal day is from 8:00 to 5:00 If a task is started at 2:00 PM Monday and finished at 10:00 AM Tuesday then the result should be 5 hours as I do not want to include any time outside of normal hours. I can figure out how to subtract dates and times but not how to bridge a day(s). My data is somewhat flexible as I have not started the project yet. I can use separate cells for the times and dates or have two cells that use both incorporate the date and time (8/27/09 2:00 PM) for start and end time or any other idea.

I have been asked to make some ammendements to a workbook currently in use.

I have to calculate elapsed time, and my formula is giving me odd results. I have a start time (cell B5), and an end time (cell F5). The formula being used was =IF(F5>0,((F5-B5)*24)) which gave the correct result. The cell is formatted as general. It didn't alot for the situation where the end time has not happened yet.

I changed the formula to =IF(F5>0,((F5-B5)*24),(K5-B5)*24) where cell K5 is the current time. The results are coming out with 6 - 9 decimal places. It makes no sense as I've tried setting the times to be exactly 24 or 48 hours to the minute. I've also tried replacing K5 in the formula to now(),

I need to calculate the difference between two cells that are formated like this: 11/10/2006 13:00. Simple subtract only works when the date hasn't changed (the subtract formula seems to focus on the time and ignore the date).

I found a formula that will work, but the results are in regular numbers, I need the hh:mm format and if I change the format of the result column, the time displayed is wrong.

The formula is=((B2-A2)*1440)/60)

If my result is 122.6 in regular numbers, when I convert to hh:mm I get 14:00.

Is there a better way to do this? Also, is there a way to eliminate weekend & holiday hours from the calculation? This is not as important as getting the results to calculate correctly in the hh:mm format.

I am attempting to pick up a date with time entry on a worksheet and place it into a TextBox on a UserForm. Format on the sheet is mm/dd/yyyy h:mm AM/PM. The UserForm is placing the value as mm/dd/yyyy 12:00 AM. here is the

Private Sub UserForm_Initialize()

If Not Range("dDate").Value = "" Then

TextBox2.Value = Range("dDate").Value

TextBox2.Text = Format(DateValue(TextBox2.Text), "mm/dd/yy h:mm AM/PM")

Else

TextBox2.Value = ""

TextBox2.SetFocus

End If

End Sub

"dDate" is the named range where the date is sitting. The format is also set on the TextBox2 exit event. Can anyone see why only the date portion is being transfered with the default 12:00 AM for no time component of the value?

I have a small project at work where I am being asked to put a simple spread sheet that will calculate a start/stop time - and also include the date. For example:

Start time 5pm, date: 3/13. The spread sheet to auto calculate what the stop time and date will be if a specific amount of hours is to be calculated. For example in this case, 12 hours. From calculating in my head that would be 5am the following day. However, how can I get this in excel to work and therefore all i would have to do is enter the start time and date, + 12 hrs, and excel would calculate the time/date after the additional 12 hrs.

I am trying to find a way to calculate the number of hours between date/times found in separate rows. The attached data set will help to envision what I am talking about.

For each couple of rows, I need to find a way to calculate the number of hours elapsed from row 1 to row 2. In the first example, to calculate the number of hours between 12/2/2009 8:56:51 and 12/4/2009 6:35:27.

I found this formula similar to other formula

NETWORKDAYS(D1,F1)-1)*"18:00"-"9:00")+IF(NETWORKDAYS(F1,F1),MEDIAN(G1,"9:00","18:00"),"18:00")-MEDIAN(NETWORKDAYS(D1,D1)*E1,"9:00","18:00")

By the way ....D1 = start Date

F1 = End Date

E1 = start Time

G1 = End Time

It's GREAT! But now I need include time from 6:00 a. m. to 10:00 p. m. (I already modified your formula:

(NETWORKDAYS(D1,F1)-1)*("22:00"-"6:00")+IF(NETWORKDAYS(F1,F1),MEDIAN(G1,"6:00","22:00"),"22:00")-MEDIAN(NETWORKDAYS(D1,D1)*E1,"6:00","22:00")) because are regular working hours in Colombia but:

1. All the days (Monday to Saturday) are working days

2. I just want to calculate the time in shifts, I don't specify the start date and end date. Example: 8:00 p.m. to 11:00 p.m. Result: 2 hours, because 1 hour is after 10:00 p.m.

This are two different options, so I need two separate formulas.

This may be a bit vague but here goes.

I have to calculate the difference between the start time and end time of a job. The only catch is, how can I avoid calculating "out of hours" time. So, if a job goes from 9am to 9am the next day, I want it to avoid calculating between the hours of 23:30 and 03:30.

Another example is if a job goes from 02:00 to 04:00, I want it to avoid the tim between 02:00 and 03:00.

If there is a difference in days, so the job goes overnight, how do I take that into consideration also.

I've got a time difference from 8:00AM - 12:30PM as 4.30 I'm trying to get the minutes, .30, converted into a 6 minute increment, .5. Is it possible to do this and if so how would it be done? Below is a chart of how the time is converted from 6 minutes increments into decimal form.

6 = 0.1 36 = 0.6

12 = 0.2 42 = 0.7

18 = 0.3 48 = 0.8

24 = 0.4 54 = 0.9

30 = 0.5 60 = 1.0

I can calculate total hours when a user enters a start date/time and a finish date/time. The kick is I only want to include hours from 2:00 PM to 12:00 AM (10 hour period). So assuming all the start and end times will be in this range, how can i calculate work hours over multiple days? For example: Start date/time = 2/26/13 2:30 PM and end date/time = 2/28/13 10:30 PM. I want my calculated hours to show 28 hours.

1. Calculate the time that has elapsed between 2 times in both hours:min (hhmm) and total mins (mm)

2. Compute the day of the week (mon-fri) a particular date fell on. I really only need to know if the date fell on a weekday or weekend.

table { }td { padding: 0px; color: windowtext; font-size: 10pt; font-weight: 400; font-style: normal; text-decoration: none; font-family: Arial; vertical-align: bottom; border: medium none; white-space: nowrap; }.xl63 { font-size: 12pt; } 1= M-F

2=S-S

3. How to write an If statement that assign a value to time based off this chart:

table { }td { padding: 0px; color: windowtext; font-size: 10pt; font-weight: 400; font-style: normal; text-decoration: none; font-family: Arial; vertical-align: bottom; border: medium none; white-space: nowrap; }.xl63 { font-size: 12pt; } 1= AM (7-1459)

2=PM (15-2259)

3= MN (23-659)

I have loaded a .csv file in which the first column contains date/times, e.g. 01/12/2012 00:00. How do I now tell Excel (2010) that this is in fact a date/time format? If I select one or more of the cells, click on the Number dialog box launcher and try to pick a suitable format tghe cells resolutely refuse to budge from being text (i.e. left-justified, still allows me to edit the 'seconds' component to a number > 60). Also which data type should I be using? The only one that appears to have a full date/time format listed is Custom (not Date or Time).

I need to determine a formula which will allow me to calculate a future date based upon a current date with varying time periods.

For example:

I have a bill which is paid on the 15th and last business day of each month. I would like to be able to see the next due date regardless of what day of the week it is.

I have a bill which is paid every other Tuesday. I would like to know the next due date without having to enter +14 for every due date in the future. In other words, it is preferable to be able to open the spreadsheet and automatically see the next due date, not use autofill to repeatedly add +14 to a previous date which would limit the # of future due dates that could be calculated.

I have a bill which is paid on the last business day of each month, not the last Friday of each month. I would need excel to return a value for the last day of the month which = Monday-Friday, regardless of what day of the week it may be as long as it isn't Saturday or Sunday(holiday exclusion would be nice but not required).
